A Boeing 747 "Jumbo Jet" has a length of 59.7 m. The runway on which the plane lands intersects another runway. The width of the

tia_tia [17]

Answer:

t = 1.48 s

Explanation:

As we know that length of the Boeing plane is

$L = 59.7 m$

width of the intersection is given as

$w = 25.0 m$

now we know that deceleration of the plane is given as

$a = -5.4 m/s^2$

Also the final speed of the plane while it clears the intersection is given as

$v_f = 53 m/s$

now we have

$d = (\frac{v_f + v_i}{2}) t$

$(25 + 59.7) = (\frac{53 + v_i}{2}) t$

also we know that

$v_f - v_i = at$

$53 - v_i = -5.4 t$

now we have

$84.7 = (\frac{53 + 53 + 5.4t}{2})t$

by solving above equation we have

$t = 1.48 s$

Charge q is 1 unit of distance away from the source charge S. Charge p is four times further away. The force exerted between S a

zhenek [66]

The correct answer is:

sixteen times

In fact, the distance between charge q and the source S is 1 unit. Instead, the distance between charge p and the source S is 4 units. The magnitude of the electrostatic force is inversely proportional to the square of the distance between the charge and the source:

$E \sim \frac{1}{r^2}$

where r is the distance. If we take the force between q and S as reference, we have r=1, so that

$E_{qS}=\frac{1}{1^2}=1$

while the force between p and S is

$E_{pS}=\frac{1}{4^2}=\frac{1}{16}$

Therefore, we see that the force exerted between q and S is 16 times the force exerted between p and S.
